Guy Takes Pregnancy Test as a Goof and Learns He Has Cancer

Like dogs, guys like to pee on new and interesting things. So when Redditor CappnPoopdeck spotted a pregnancy test that his ex-girlfriend had left in his medicine cabinet, the urge to urinate on it and see what would happen was obviously pretty overwhelming.

"You may have testicular cancer! Get to an oncologist, tell them you took a pregnancy test and it came out positive," he wrote. The science behind this internet diagnosis is pretty solid, as many testicular cancers produce the same pregnancy-test triggering hormone that a placenta would.

Nervous, CappnPoopdeck went to his doctor. And, yes, it was testicular cancer.

Luckily -- and thanks to reddit -- the growth was caught in its early stages. He will probably lose a ball but is also looking at about a 99 percent survival rate.

Moral of the story: the next time you feel the urge to pee on something unusual and tell your friends about it don't hold back. It just might save your life.
